Recovery of a coherent system in the presence of an uncorrectable error

摘要: A system, and corresponding method, is described for correcting an uncorrectable error in a coherent system. The detecting using code, such as parity or SECDED. cache controller agent calculates set of possible addresses. directory queried to determine which one the addresses correct address. and/or updated with address way. invention can be implemented any chip, HDL code that perform protection schemes require ECC calculation, kind. Embodiments enable IPs use different protections reduce power consumption bandwidth access more efficiently errors avoid system restart when occurs.
